# In order to cross-compile node for Android using NDK, run:
#   source android-configure <path_to_ndk> [arch]
#
# By running android-configure with source, will allow environment variables to
# be persistent in current session. This is useful for installing native node
# modules with npm. Also, don't forget to set the arch in npm config using
# 'npm config set arch=<arch>'
